Refactoring – Stay Quick and Beautiful

Sometimes you have to refactor something.  It may seem like it works, but the code is horrible-looking and inefficient. Consider for example this gem: No documentation, missing @Override annotation, quadratic blow-up of something that should be linear, unmotivated cloning of an immutable class, over-shadowing of field variables, leading to a clumsy syntax, and a code-structure […]

Modular Declare

This week I am in Nijmegen with the purpose of integrating Declare and iTasks. The idea is to allow components in either language to be used as sub-components in either.  This makes it possible to mix paradigms (declarative and functional workflow modeling), introduces modules in Declare, and makes Declare (and iTasks) distributed. We are still […]
